North Avenue / Quezon City Airfield

The primary reason for closure was rapid urban expansion and the strategic redevelopment of Quezon City. The airfield was situated on what became extremely valuable real estate designated to be the city's new Central Business District (Triangle Park). The land was expropriated and repurposed by the government for large-scale commercial, residential, and critical infrastructure projects, making a general aviation airfield in that location untenable and incompatible with the city's master plan.

The site of the former airfield has been completely transformed and is now one of the most significant commercial and transportation hubs in Metro Manila. The land is occupied by several major developments, including:

- **Vertis North:** A large, mixed-use estate by Ayala Land that includes the Ayala Malls Vertis North, high-rise residential condominiums, and office buildings.
- **Trinoma Mall:** A large shopping mall located adjacent to the former airfield's grounds.
- **North Triangle Common Station:** A massive, unifying station currently under construction that will connect four major railway lines (MRT-3, LRT-1, the future MRT-7, and the Metro Manila Subway).

The entire area is part of the 'Triangle Park' or Quezon City Central Business District, located at the intersection of two of the city's busiest thoroughfares, EDSA and North Avenue.

The North Avenue Airfield was a significant general aviation hub in the post-WWII era, particularly from the 1960s through the 1970s. It was not a major commercial airport for passenger airlines but served as a base for:

- **Flight Training Schools:** It was a primary training ground for aspiring pilots in Metro Manila.
- **Private Aircraft:** It housed and serviced privately-owned single-engine and twin-engine aircraft.
- **Charter and Air Taxi Services:** Companies operated small aircraft for on-demand flights to various destinations across the Philippines.
- **Aircraft Maintenance:** It had facilities for the repair and maintenance of light aircraft.

It played a crucial role in the development of the Philippines' private aviation sector during a time of economic growth. The ICAO code 'PH-0248' is an unofficial identifier, likely assigned by aviation enthusiasts or flight simulator database creators, as the airfield was closed before the modern standardized system was universally applied to such small fields.

There are zero prospects for reopening the airfield. The land has been irreversibly and densely redeveloped with high-rise buildings, massive commercial centers, and critical public transportation infrastructure. The airspace is now obstructed, and the land value is among the highest in the country, making any future aviation use physically and economically impossible.
